Hello there!
I Have read your national standard 2720 part 27 in which are presented different methods for determination of sulphates .
I am interesed about the Volumetric Method in which ia presented a formula for the calculation of the sulphates:
0.0177*100(x-y)
I wish to know how the term 0.0177 was determinated or what does IT represent¿???
Thank You în advance!!?
